Paper Abstract

A procedure for synthetic aperture radar (SAR) raw data generation for moving ships on the ocean is proposed, which combines the raw data simulation of the time evolving sea and the moving ships. The raw data of the ocean and the ship are simulated under the uniform coordinate system, respectively. The desired SAR signal is obtained by vector summation. For the ocean SAR raw data simulation, the dynamics and time-variant reflectivity function are taken into account. Moreover, an efficient and accurate algorithm with time-domain integration along range dimension is adopted. For the ship raw data simulation, the ship's six degrees of freedom movement driven by the time-varying ocean waves as well as the translation of the ship on sea surface are considered. Simulation results are presented to demonstrate the validity and applicability of the proposed techniques.
